The key application scenario of wireless sensor networks is data gathering: sensor nodes transmit data, possibly in a multi-hop fashion, to an information sink. The performance of...
Abstract— In wireless sensor networks, one of the big challenges is to achieve a satisfactory network lifetime while meeting quality of service (QoS) requirements. In this paper,...

Wireless sensor networks (WSNs) are known to be highly energy-constrained and each network’s lifetime has a strong dependence on the nodes’ battery capacity. As such, the netw...
Until practical ad-hoc localization systems are developed, early deployments of wireless sensor networks will manually configure location information in network nodes in order to...
Sensor deployment is a critical issue, as it affects the cost and detection capabilities of a wireless sensor network. Although many previous efforts have addressed this issue, mo...
